A mixture of 2-Chloro-4,6-dimethyl-pyrimidine (92 mg, 0.645 mmol, 1 eq.), 3-aminobenzene boronic acid (100 mg, 0.645 mmol, 1 eq.), Na2CO3 (137 mg, 1.29 mmol, 2 eq.), and Pd(PPh3)2Cl2 (23 mg, 0.032 mmol. 5 mol %) in a 1:1 v/v mixture of CH3CN/H2O (2.6 mL) is purged with N2 for 5 minutes and then heated in a microwave at 150° C. for 5 minutes. After cooling to room temperature, the reaction is diluted with EtOAc and sequentially washed with saturated aqueous NaHCO3 and saturated aqueous NaCl. The organic solution is dried over Na2SO4. After concentration, the residue is purified by silica gel chromatography (1:1 hexanes/EtOAc) to give 3-(4,6-Dimethyl-pyrimidin-2-yl)-phenylamine as a yellow semisolid. [MS: (ES+) 200.1 (M+1)+].
